: I APPARATUS FOR SEPARATING SOLID PARTICLES FROM GASEOUS FLUIDS.

v SPILsBURY, a citizen of the United States, and a resident of the city of New Rochelle,

separating of soli gaseous fluids as 1s necessary 1n the metalin the county of Westchester and State of New York, have invented certain new and useful Improvements in Aipparatus for Separating Solid Barticles r Fluids, of which the following is a speclfication, reference being had to the accompanying drawings, forming a part hereof.

This invention or heavy particles from lurgical processes fox instance in the obtaining of zinc or lead oxids from the gases which emanate from the furnaces and it is also applicable to the separating of foreign matter from gaseous fluids as for example such matter as dust from air or the heavy particles from smoke and the like.

Another feature of this invention relates .to the separating of solidmatter from gaseous fluids by forcing the fluids through a porous rigid septum which in devices used in metallurgical processes must generally possess heat and acid resisting 'qualities. The septum utilized in the construction described is a porous silica sponge but it is to be understood that the invention is 'not limited .to this particular element as any other filtering medium may be utilized which possesses substantially the same characteristics and accomplishes the purpose in a proper manner.

Another feature of the invention relates to the separating of the deposited particles from the se tum preferably by forcing or drawing fluld through the septum in a direction reverse to that in which the gases flowed at the time the heavy particles were 7 being deposited thereupon.

showing one embodiment of ap aratus for carrying out the invention, re erence is made to the drawing forming a part of this specification.

I Figure 1 rep-resents a transverse view of theapparatus. Fig. 2 represents a sectional plan View, a ortion of the same showing the cell with t e covers on part of the cells,

with the covers removed from another part of the cel s, with a hood over still another part and the portion at the extreme right showing the arrangement of plates at-the lower portiohof the cells. Fig. 3 isa sec-openings in the adjoining om Gaseous particularly relates to. the

tional view taken along the line 3 3 in Fig. 2. Figft shows the detail construction of a section of the filtering se tum and the corner member therefor. Flg. 5 shows a detail of the supporting late resting upon an I-beam and Fig. 6 s owe a detail of the cover plate.

It will be mentioned that are not intended to illustrate an apparatus complete in all its accessories but is simply designed to illustrate the essential features of the invention.

In the drawings a represents one end of the structure from which the gaseous fluids containing the heavy particles are to be forced by the fan or blower member I) through the flue c and from thence through the tube ll having the gate d for shutting off the particular chamber which may be one of a battery of chambers, when desired. The filtering chambers may be formed similar to those at present having the ordinary side walls and these side walls carry supporting beams 9 upon which rest the base plates h. These base plates are so arranged that there are solid and open portions alternating and .around each of the openings there extends a vertical tier of filtering septums, composed of plates mI'held together by corner pieces 70 (Fig. 4), closed at thetop by cover plates 1' which are removable. It will be apparent that this arrangement constitutes a cell structure into the drawings serving as a means which the gases can enter and' through the walls of which the gases may be forced. The material of the septum is preferably a silica sponge in the present apparatus but the septum may be of any material which is porous and rigid, is capable of withstand ingthe deleterious effect of heat or acids, when necessary to withstand the same, and which is suiiiciently porous to permit suflicient flow of gases therethrough in order to accomplish the purpose. 'It will also be noticed that the cell structure is composed of a series of vertical cells alternately open a and closed at the top, those cells which are closed at the top being open at the; bottom. The advantage'of this arrangement is this, that the gases entering in the lower part of the chamber can pass upwardly into the cells which are closed at the top and be filtered by the vertical walls thereof through which the gases flow, and pass out of the cellsht the top thereof leaving the deposits upon the inte rior walls of the cells which are closed at the top. 3y the lorcing ot a fluid through the septum in a reverse direction it is apparent that; the deposited matter will be= forced therefrom and when this is done with the septum .in. place the deposits will naturally drop and he received .in the chamber 1: from which the can be removed by an) suitable manner as by \rorlnnen who can enter through the door I). The upper portion of the chamber is covered by the hood n and the liltered gases can escape by means oi the chimney or llue 0. There are also car rled by the walls; the balconies c and c from which one can enter through the doors j i or ,1 to the interior ot the chamber in order to do any wort: that is necessary therein as for example. removing or replacing any of the parts of the filtering device. The fan I) is reversible so that it can. either force the gases through the medium or can create suction sutlicient to cause a tlowage o't tiuid as air in a. reverse direction therethrough sulliclent; to cause a removal of the deposits therefrom after the solid matter has collected on the same sutlicient to cli'ect its.

septum and means for forcing the tluid through the septum.

1-. In a device for separating solid particles from gaseous fumes, a filtering chamber containing a diaphragm of rigid sponge septum and means for forcing the fumes through the septum.

- 5. In a device for separating particles :trom gaseous tumes, a chamber lnclosing littering septums ot rigid sponge and means for forcing 'the tumes through the septum,

the littering septnms extending at angles to each other.

6. In a device of the character described, a chamber containing rigid diaphragms and means for blowing the gaseous fumes through the diaphragm at one time in order to remove particles from the fumes and for -ausing a suction to draw tluid in a reverse direction through the diaphragm to remove the deposited particles from the diaphragm at another time.

7. In a device of the class described, a separating means composed of porous cells, part of which have inlet and the others of which have exit openings, the cells being so arranged that a gaseous mixture can enter an inlet opening of one cell, pass through the side walls of such cell then ott' through the exit openings of adjacent cells.

8. In a device of the class described, a cell delincd by vertically extending rigid mineral sponge elements provided with a cover and open at the bottom.

5). In a device of the class described, a cell defined by vertically extending rigid mineral sponge elennznts, open at the top, and closed at the bot tom.

10. In a device for filtering tum. formed of rigid sponge above the other.

11. In a device for filtering tum formed of rigid sponge a t the side of the other.

12. In a device for filtering fumes, :1 Septum formed of rigid sponge members one supported by the other.
